Abstract (en)
[origin: DE10160720A1] The invention relates to a cosmetic agent containing at least one water-soluble or water-dispersible copolymer which can be obtained by radical copolymerisation of at least one N-vinyllactam, at least one anionogen monomer and optionally other copolymerisable alpha , beta -ethylenically unsaturated compounds, in the presence of a polymer constituent having repeat units which comprise ether groups or which are derived from vinyl alcohol.
[origin: DE10160720A1] New water-soluble or -dispersible copolymer (I) is produced by polymerizing an N-vinyl lactam and a comonomer, in the presence of a polyether or polyvinyl alcohol, and polymerizing an anionic monomer in the presence of the product. New water-soluble or -dispersible copolymer produced by a two-stage radical polymerization of a monomer mixture comprising (wt.%): (1) N-vinyl lactam (20-99.9); (2) an alpha , beta -unsaturated anionic monomer (0.1-30); (3) a monomer of formula (II) or (II) or an alpha , beta -unsaturated anionic or cationic monomer (0.1-65); and (4) comonomer(s) (0-15). The polymerization is in the presence of a polyether or a polymer (5) comprising at least 50 wt.% vinyl alcohol units. Monomer (1) and at least part of monomer (3) are polymerized in the presence of at least part of component (5), after which monomer (2) and optionally (4) and any remaining monomer (3) and component (5) are added and polymerized. R1 = CH2=CR3; R3 = H or 1-4C alkyl; R2 = H, alkyl, hydroxyalkyl, aminoalkyl, N-alkylaminoalkyl, N,N-dialkylaminoalkyl or a polyether group of at least 5 alkylene oxide units; X = O or NR4; and R4 = H, 1-7C alkyl or a polyether group of at least 5 alkylene oxide units. An Independent claim is also included for a cosmetic or pharmaceutical composition comprising (I).
